I work in an alcoholic beverage (spirit industry) and we use liquid nitrogen during packing while use in tetra and would request for a test to know the purity of nitrogen gas in alcoholic beverages.

Dear njrsbaby,

 

May be simpler to get a supplier's analysis certificate from an accredited lab. Or submit a sample yourself.

 

Not my product area but evaluation of purity of very high grade compounds is usually focussed on measuring the typical impurities followed by subtraction from 100%.
